Postscript also does lines and circles and ...
Usually it gets (much) better results with text than you get from gif/jpg
when they are targeted for screen resolution.

Keep in mind that the scale factor may be a bit off. If you draw a 1 inch
line, it might be slightly more or less than an inch.
It's easy to scale postscript. My linux system has a psresize command. (I
haven't tried it, at least not recently.) With a bit of trial and error, you
can get a very accurate result.
I used to print gerber layers for PCBs on mylar. If you were doing
mechanical checks, it was worth the effort to get the scale right. (Maybe we
just had a crappy printer.)
If you like low level hacking, you can write raw postscript by hand for
simple things. I have the first 3 postscript books from many years ago. I
pull them out every few years.
